What is DKA?

Diabetic ketoacidosis (DKA) is an acute complication of hyperglycemic crisis in patients with diabetes. It's a life-threatening complication that's most common in patients with type 1 diabetes and is sometimes the first evidence of the disease.

It may result from infection, illness, surgery, stress or insufficient or absent insulin.

Chest X-ray

During chest radiography (aka chest X-ray), X-ray beams penetrate the chest and react on specially sensitized film. Normal pulmonary tissue is radiolucent while abnormalities such as infiltrates, foreign bodies, fluid and tumors appear dense. That is why they are detected through X-rays.
